Usage Precautions 1-5
Handling precautions
a. When you use the JP-K60, JP-F63, JP-K68, JP-K70, JP-T71, JP-K77,JP-E78,
JP-K81, JP-K84 or JP-B85 ink, you must complete the print head air-purge
procedure without regard to the humidity predominating in the employed
environment.
(See Section 1.2.6, "Print head air purge".)
b. (1) The JP-K60, JP-K69, JP-K84 and JP-K106 inks employ carbon black as the
pigment.
If an excess electrostatic charge alarm is issued when no ink or makeup ink
is on the print head surface and ink drops are properly generated, it is
conceivable that carbon black may be deposited on the print head surface.
This may have been incurred by creeping leakage on the deflection
electrode mounting surface. In such an instance, remove the deflection
electrode from the printer head and wipe the entire mounting surface clean.
(2) The JP-K60, JP-K69, JP-K84 and JP-K106 inks employ carbon black as the
pigment.
Shake the ink bottle well before use.
c. If the dye of the JP-K60 comes into contact with the human body, it cannot
easily be removed. Exercise utmost caution to avoid skin contact with it.
d. The JP-K65 hardens if it is exposed to ultraviolet rays after printing.
Its hardenability varies with the printed matter material and surface condition
(roughness and presence of deposits), printed matter temperature, time interval
between printing completion and ultraviolet radiation, employed ultraviolet
radiation device, and other factors. You should confirm the ink hardenability
under the employed operating conditions.
Typical hardening conditions
Lamp type Metal halide lamp (2kW)
Lamp light emission length 250mm (80W/cm)
Radiation distance 150mm
Radiation time 15seconds
If ink sticks to the end of the nozzle, the ink stream will be bent, the nozzle may
be clogged, or printing disorder may be caused. Before ejection, apply the
makeup ink to the orifice plate to wash it.
e. If JP-F63, JP-F92, JP-F97 has been deteriorated by light (corresponding to the
irradiation of sunlight for one month or more), light emission by ultra violet rays
becomes difficult. However, this condition can be improved into a light emission
enable status by applying a regenerating liquid (type: RF-B1, code No.: 451520,
type: RF-P2, code No.: 450260).
Placing JP-F63, JP-F92, JP-F97 in an environment of direct sunlight may cause
ink deterioration and lowering of the light luminescence intensity. Keep the
product tightly sealed and stored in a dark cold place (0 to 20
℃
)
